array_to_string return is different between Windows and Linux systems

Hi all,

The array_to_string function used to compare the content of arrays of doubles doesn't return the same result if the OS is Windows or if it is a Linux system.

Here is an example using the same table content:
Result 1: "0,0.000263,8e-06,8e-06,0.000146,0.000321" [PostgreSQL 8.0.4 (redhat) or 8.1.5 (OpenSuse 10.2)]
Result 2: "0,0.000263,8e-006,8e-006,0.000146,0.000321" [PostgreSQL 8.1.4, 8.1.5 or 8.1.6 (Windows)]
The string compare fails!

Is there a way to fix the exponent size ?
